We provide an analysis of Greenland temperature records to compare the current (1995–2005) warming period with the previous (1920–1930) Greenland warming. We find that the current Greenland warming is not unprecedented in recent Greenland history. Temperature increases in the two warming periods are of a similar magnitude, however, the rate of warming in 1920–1930 was about 50% higher than that in 1995–2005

Thanks go out to commenter Lanevn for bringing this to our attention. Some of the data concerning last summer's impact on the Greenland ice sheet has been released in a first paper by M. Tedesco, X. Fettweis, T Mote, J. Wahr, P. Alexander, J. Box, and B. Wouters: Evidence and analysis of 2012 G...
